Outcome of Anterior Cruciate Ligament Reconstruction using Femoral Intrafix for a Single Tunnel Double Bundle Anterior Cruciate Ligament Reconstruction

Abstract

Background: Single-tunnel double-bundle anterior cruciate ligament reconstruction (ACLR) withanatomical placement of hamstring tendon graft can closely restore the anterior knee instability whencompared with single bundle reconstruction.Aim: Evaluation of the clinical and functional outcomes of ACLR using femoral intra-fix and tibialinterference screw.Methods: This is a prospective study held on 40 patients who underwent autologous hamstring graft ACLRusing femoral intra-fix and tibial interference screw. After a median follow up of one year the clinical(Lysholm score), functional outcome (International Knee Documentation Committee, IKDC) and Jointlaxity (assessed with KT-1000 arthrometer - MEDmetric, San Diego, CA) were evaluated.Results: As regard IKDC 36 patients (90%) had normal or nearly normal knees postoperatively incomparison to 100% had abnormal and severely abnormal knees pre-operatively (P value < 0.001). Themean Lysholm score was higher in the postoperative follow up than preoperative (91.40±7.3 Vs 53.35±13.55) with statistically significant (P value < 0.001). The mean anterior translation of tibia improved from7.55 mm preoperatively to 2.1 mm after one year of ACLR.Conclusion: ACLR using femoral intra-fix and tibial interference screw provide secure graft fixation andallow early rehabilitation. The clinical and functional outcome of this fixation technique is rewarding.
